One of the common fungal disease of man is

  1. Cholera

  2. Plague

  3. Typhoid

  4. Ring worm


Correct Option: D

  • Ringworm is actually a skin infection caused by fungus. No worms involved. The name “ringworm” probably comes from the rash that many people see. On the skin, the rash often has a ring-shaped pattern and a raised, scaly border that snakes its way around the edge like a worm. Ringworm is common.
  • Cholera is an infectious disease that causes severe watery diarrhoea, which can lead to dehydration and even death if untreated. It is caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae.
  • Typhoid fever, also known simply as typhoid, is a bacterial infection due to a specific type of Salmonella that causes symptoms.
  • Plague is a disease that affects humans and other mammals. It is caused by the bacterium, Yersinia pestis. Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with the plague.

  • Typhoid fever is caused by Salmonella typhi bacteria.
  • Parkinson's disease (PD) is a neurodegenerative disorder that affects the nerve cells in the brain that produce dopamine. It is not caused by bacteria or fungi.
  • Cancer results when cellular changes cause the uncontrolled growth and division of cells, hence it is not caused by any infectious agent.

Hence answer is 'Ergot'

A fungal disease of humans is due to :

  1. Typhoid

  2. Trichophyton

  3. Microsporum

  4. Both B and C


Correct Option: D
Explanation:
  • Typhoid is an enteric fever caused by the bacterium salmonella thyphi. Hence typhoid is not a fungal disease.

  4. Ascaris - a roundworm


Correct Option: C
Explanation:
  • The pathogen Microsporum responsible for ringworm disease in humans belongs to the same kingdom of organisms as that of Rhizopus - a mold(a fungus that grows in the form of multicellular filaments called hyphae)because both Microsporum and Rhizophus belong to kingdom Fungi.
  • So, the correct answer is 'Rhizopus - a mould'.
